"Scientists in China have developed a strong, highly conductive carbon yarn that could be used to make spacesuits, bullet-proof vests, and radiation suits."
"Now scientists in China reveal they have made composite yarns from carbon nanotubes and plastic that are both very strong and electrically conductive. The researchers first wove pure carbon nanotube yarns as free of physical defects as possible, to ensure it had good electrical conductivity. They next impregnated a strengthening plastic into the empty spaces inside this yarn, using a solvent that did not leave any leftovers behind that would detract from the yarn's electrical properties. The strength of these new yarns—up to about five times stronger than steel—combined with their flexibility makes them attractive for protective fabrics such as bulletproof vests."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
